With the rising Islamic emotions in people, we find rulers trying to fool masses regarding what an Islamic State is. As an example Imran Khan tried to gather support with the slogan 'Riyasat e Madina'. Similarly some people think Saudi is due to its services for Hajj and Umrah. While some take Iran as Islamic based on some Islamic symbols.
So it is important to understand what really is the definition of an Islamic state? What are the conditions a state needs to fulfil to qualify as an Islamic State? And whether any of the current states fall in this category?
